The United States and the United Kingdom are planning to extend their 1958 Mutual Defence Agreement (MDA) indefinitely, according to the Financial Times. This agreement, which governs technology sharing between their nuclear weapons programs, was last renewed in 2014 for a ten-year period. The extension comes as both nations embark on costly modernizations of their nuclear deterrent to counter arms proliferation by adversaries. The decision to make the MDA permanent reflects the strategic importance of continued military cooperation and technology sharing between the two allies.
